<p>首先我们讲一下工作原理:</p>
<p>服务器开机后(加载完毕/etc/rc.d/rc.local后)</p>
<p> 读取timer单元 -&gt; 等待启动服务 -&gt; 程序模拟登录 -&gt; 获取课表信息 -&gt; 数据处理 -&gt; 发送邮件 </p>
<p><strong>工欲善其事必先利其器</strong></p>
<p>需要的硬件设备：</p>
<p>1.一台可以写代码的电脑,用来编写代码管理服务器</p>
<p>2.一台本地服务器，或者云服务器,用来运行代码</p>
<p>运行需要的系统环境:</p>
<p>linux系统即可:ubuntu,debian,centos等…</p>
<blockquote>
<p>需要注意的是，本文采用Systemd进程管理来实现目的，老系统的init程序有的是SysV类型和Upstart类型。</p>
</blockquote>
<p>然后编写获取课表信息的代码:</p>

<p>然后我们配置一下服务器上面的环境:</p>
<p>1.安装python3,pip3</p>
<p>2.安装bs4,requests</p>
<p>2.检查systemd是否能正常开启服务单元</p>
<p>3.检查邮件模块是否需要安装相关依赖包</p>
